Recently I bought a vintage finishing book. It has a page on wrinkle 
finish."The Complete Book of Wood Finishing," by Robert Scharff, 
copyright 1955, pages 204 and 205. It says:

"Wrinkle Finishes

"Wrinkling lacquer is used on a wide variety of products in both wood 
and metal. It can be obtained in all colors, in a range of patterns from 
coarse to fine wrinkles, for air drying or baking. It is variouly known 
as fingerprint, shrivel, ripple, etc. Because of its rough texture, 
wrinkle is a one-coat finish since the surface to which its applied need 
not be smooth. The material is heavier than ordinary lacquers and can be 
brushed on quite satisfactorily. If a spray gun is used it should be 
applied by pressure feed. Thin slightly with naphtha if required. The 
heavier the coat, the coarser the wrinkle; very thin coats will not 
wrinkle at all. Heat is necessary for the wrinkles to form, and even 
with the air-dry wrinkling lacquer, exposure before a  gas or electric 
heater will give a quicker and more uniform pattern. Small objects can 
easily be baked in an ordinary kitchen oven. Air-dry the piece for about 
half an hour to permit partial evaporation of the solvent. Then bake at 
a temperature of about 180 degrees for about 1 hour or until the 
wrinkles are well formed. Increase the heat to 250 degrees for about 2 
hours to harden the finish coat. No top coat is necessary. However, if a 
colored finish other than the wrinkle color is required, apply any color 
of lacquer enamel. The finish coat can be smutted or a shaded effect can 
be obtained by spraying a contrasting color enamel with the gun held 
close to and parallel with the work surface. This deposits the enamel on 
only one side of the wrinkles and gives a novel two-tone surface."
